I Want You (She's So Heavy)

"A fascinating song, very indicative of John's mood at the time - he was consumed with all things Yoko.

"It goes from hard rock to almost jazzy, bossa nova. Of course, there's the famous ride-out, the riff being repeated many times. George put some very intense Moog sounds down and Ringo played with a wind machine - the whole thing grew louder and louder till it got close to a breaking point.

"I thought the song was going to have a fade out, but suddenly John told me, 'Cut the tape.' I was apprehensive at first - we'd never done anything like that. 'Cut the tape?' But he was insistent, and he wound up being right. The track, and side one, ends in a very jarring way."
